## Summary description

SpiroFlex steel smooth duct pipe 150 mm (model SX-WK150SG) is a 1 m section of smooth-walled round ventilation or flue ducting. Made of steel for rigidity and durability, it suits HVAC and exhaust systems where a 150 mm diameter smooth pipe is required. Use for air distribution, ventilation runs, or connecting fans and appliances.

## Long description

SpiroFlex steel smooth duct pipe 150 mm, model SX-WK150SG, 1 m length is a smooth-walled circular section intended for ventilation, exhaust and flue systems that require a rigid steel duct with a 150 mm internal diameter. The 1 metre straight pipe provides a stable, low-resistance airflow path for distribution ducts, fan connections and appliance outlets. Constructed from steel, the tube is designed for durability and dimensional stability in standard HVAC and extraction applications.
Advantages
The smooth internal surface reduces friction and pressure loss compared with corrugated alternatives, improving airflow efficiency in ventilation runs. Steel construction offers mechanical strength, good resistance to deformation and stable connection interfaces for clamps or fittings. A 150 mm diameter is a common size for domestic and light commercial systems, enabling straightforward integration with compatible couplers, collars and fans.
Suitable for
 Ventilation ducts in residential and light commercial buildings
 Connecting extract fans, range hoods or inline fans to ductwork
 Short straight runs or linking segments between fittings
 Exhaust or flue outlet sections where steel material is required
When it may not be suitable
This steel smooth duct pipe is not intended for highly flexible routing where multiple bends or tight turns are required; rigid sections are best for straight or gently curved layouts. It is also not a finished exterior weatherproofing solution — additional insulation or protective cladding may be necessary for outdoor or exposed installations where corrosion or heat loss is a concern.
Key specifications
 Shape: Circular smooth-walled duct
 Nominal internal diameter: 150 mm
 Length: 1 metre
 Material: Steel (rigid construction)
 Surface: Smooth internal surface for reduced airflow resistance
How to use
Install the pipe as a straight section within the ventilation run, aligning ends with adjacent ducts, collars or fittings. Secure joints with appropriate clamps, self-tapping screws or duct connectors designed for metal ducts to ensure airtight connections. For best performance, maintain gentle alignment to minimize abrupt direction changes and seal joints with suitable duct sealant or tape where required. When connecting to appliances or fan units, follow manufacturer mounting clearances and airflow direction recommendations.
What to consider before purchase
 Confirm the required internal diameter is 150 mm to match existing fittings and fans
 Check the planned run length and number of straight sections needed versus bends and transitions
 Ensure material choice (steel) suits the installation environment and corrosion considerations
 Verify compatibility with available clamps, collars and sealing products for metal ducts
Usage recommendations
Use this 150 mm SpiroFlex steel smooth duct pipe for straight, low-resistance sections of ventilation or exhaust systems. Combine with purpose-made metal connectors and sealants, avoid excessive bending, and consider insulation or protective coating if the pipe will be exposed to moisture or outdoor conditions.
